Give more detail on that - I don't see it in the screenshot provided.

But what the screenshot does show is that your target has no power:

Hi @claudenesta 

This is normal. STM32MPU product doesn't support flashing through ST-LINK

You might use USB boot. 

Check-out STM32MP257x-EV1 - stm32mpu

@Olivier GALLIEN 

Thank you for your feedback, but what I mentioned early is running the code through the board using STM32CubeIDE, about flashing is already done with stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06 Starter package, is where I have used USB boot mode. 

see the screenshot below:

And I was thing that it is because of in STM32Cubeprogrammer does not find the STM32 Target to be connected.

I think its clear now.
